Re: DetroiTug's Tug is going together

Margaret S has a very good refrigeration system, although it requires the steam plant to be in operation for functioning. The sidewheeler is Propane fired, with burners supplied from standard 20 pound barbecue cylinders. Placing the 20 pound Propane cylinder in an insulated cooler case, the Propane ...

Re: A new-old 25' launch

Beautiful old hull, love the traditional form. What is the intended restoration method? You could sink a small fortune of labor into replacing things as original, or spend far less encapsulating the hull in fiberglass. Both methods have their advantages and troubles.

Re: SPIRAX SARCO - The Boiler House

For many years I have used Sarco Thermodynamic Traps to automatically control the water level in my boilers. Mounting the Thermodynamic trap on a tee fitting, in parallel with the boiler center "try cock", will prohibit the boiler water level from rising above this point. When the boiler water level...

Re: Hot wells

A tall/low free surface area (air/water interface area) hotwell tank will amplify the level changes that occur in the boiler, and can therefore attain more reliable float actuated bypass valve action. Also the float valve action will be less susceptible to rocking and rolling of the boat in rough se...

Re: Hot wells

Consider the two relevant hotwell tank vs. boiler free surface areas. One issue that should be considered is the hotwell tank air/water interface area compared to the boiler steam/water interface area. When steaming along with the feed pump bypassed, the water level in the boiler will go down, with ...

Re: Steam engine from the North Caucasus

Yes, I had seen a build sequence with photographs on another (or this?) website where two of these boilers were being fabricated in England. My drawing neglected to show a row of short downcomers between the two large drums (my bad). This configuration can be made virtually as long as desired, and f...

Re: Show us your jewelry

Those lamps are real inspirational beauties. I traded my good Lukenheimer steam whistle for a similar set of kerosene running lights (avoid electricity on a steamer, dangerous unknown stuff), but have yet to restore them. I guess I have to get to work on cleaning up my antique running lights.

Re: Steam engine from the North Caucasus

I was just preparing a drawing of this type of boiler when DetroitTug posted the picture of it. This is the most appropriate launch boiler if no welding is required, and many have been made in this form for several years. Tubes are rolled in, and this can withstand 20 atmospheres easily. Steel rolle...

Re: Steam engine from the North Caucasus

Watertube boilers can be made with no welding, by use of tubes rolled into the larger drums. Large drum ends can be closed with a steel plate and gasket, held with strength by stay-bolts. These designs are reliable. You need a tube bending tool that can be made with your machine tools, to bend the w...

Re: Stuart no 6

dampfspieler, you have an excellent method of clamping the valve travel block to the valve rod, with infinite precision available for fine adjustment. I will follow that method on one of my future builds. For small engines, I have made the valve rod longer, allowing bearing support at both ends of t...
